WebSpherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed … WebExample 1: find a side given the angle and the hypotenuse. ABC is a right angle triangle. The size of angle ACB = 60º and the length BC = 16cm. Calculate the value of x. Labelling the sides OAH in relation to the angle 60º, we can use the hypotenuse, and we need to find the adjacent side. We therefore need to use the cosine function.
